Abstract
Embodiments include apparatuses and methods related to a compound varactor. A first varactor in the compound varactor may include a collector layer and a first base layer that is arranged in a first plurality of parallel fingers. A second varactor in the compound varactor may include a second base layer arranged in a second plurality of parallel fingers, and the base layer may be coupled with the collector layer. In embodiments, the fingers of the base layers of the first varactor and the second varactor may be interleaved with one another. Other embodiments may be disclosed or claimed herein.
Claims20
An apparatus comprising:
- a first diode that includes a first base layer arranged in a first plurality of parallel fingers defining a first plurality of spaces, and a collector layer coupled with the first base layer;
- and
- a second diode that includes a second base layer arranged in a second plurality of parallel fingers defining a second plurality of spaces, and the collector layer that is further coupled with the second base layer;
- wherein a first finger in a first plurality of parallel fingers is in a first space in the second plurality of spaces, and a second finger in the second plurality of parallel fingers is in a second space in the first plurality of spaces.
A system comprising:
- a first varactor pair that includes a first base layer arranged in a first plurality of parallel fingers, a second base layer arranged in a second plurality of parallel finger that are interspersed with the first plurality of parallel fingers, and a first collector layer coupled with the first base layer and the second base layer;
- and
- a second varactor pair that includes a third base layer arranged in a third plurality of parallel fingers, a fourth base layer arranged in a fourth plurality of parallel fingers interspersed with the third plurality of parallel fingers, and a second collector layer coupled with the third base layer and the fourth base layer.
A method comprising:
- depositing a collector layer;
- depositing a first base layer arranged in a first plurality of parallel fingers directly onto the collector layer;
- and
- depositing a second base layer arranged in a second plurality of parallel fingers that are interleaved with the first plurality of parallel fingers directly onto the collector layer.
